ABSTRACT:
A jack-up offshore drilling or production oil platform of the type including a barge (1) mounted so that it can be moved between a position for floating and a position for production out of the water. The barge is moved along bearing legs (2) by means of drive mechanisms (10) which each include at least two opposed sets (11). Each set is formed of a motor (12) associated with at least one set of reduction gears (13) driving, via a shaft, an output pinion (15) interacting with opposed racks (16) mounted on the bearing legs (2). Each rack (16) is provided along a length of the corresponding leg (2) necessary for moving the barge (1) between the position for floating and the production position. Also provided are devices for controlling the lowering of each leg (2) as far as a bearing structure (6) or as far as a seabed (7).
